JOHN ROSBOROUGH, OF STVLOUIS, MISSOURI, ASSIGNOB, OF ONE-HALF TO LOUISA. MANEWAL, OF SAME PLACE.

CAKE-ICING MACHINE.

SPECIFICATION forming part of Letters Patent No. 681,929, datedSeptember 8, 1901. Application filed February 4, 1901. Serial No. 45,91.(N model.)

To all whom it may concern:

Be it known that 1, JOHN ROSBOROUGH, a citizen of the United States,residing in the city of St. Louis, in the State of Missouri,

have invented certain new and useful Improvements in Cake-IcingMachines, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this speciro fication.

My invention relates to a machine for applying icing to cakes, themachine being so constructed that the cakes are automatically droppedinto clamping and carrying means I 5 and conveyed to aposition beneaththe icingcontaining receptacle, where thejioing is deposited on thecakes and the surplus of icing is removed, after which the cakes areautomatically delivered from the machine.

My invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims.

1 Figure I is a view partly in side elevation and partly in verticalsection. Fig. 11 isa view partly in side elevation and partly invertical section looking at the machine from a position at right anglesto that in Fig. I. Fig. III is a top or plan view. Fig. IV is a side oredge view of the upper delivery-chute.

0 Fig. V is a top view of the upper deliverychute. Fig. VI is a detailview of one of the cake-carriers.

1 designates the main frame of the machine, having a lowerarm 2 and anupper arm 3 5 3, the latter of which is provided with adownwardly-extending leg 4:.

5 designates a drive-shaft mounted in a suitable bearing in the mainframe 1 and in a box 6 on the lower arm 2. The drive-shaft 5 is equippedwith suitable pulleys 7 and carries upon its inner end a beveled pinion8.

9 designates a vertical shaft mounted in suitable bearings in the lowerand upper arms 2 and 3 and equipped with a beveled pinion 10, thatmeshes with the pinion 8 for the purpose of driving said vertical shaft.Fitted upon the vertical shaft 9 are collars 11, each of which hasattached to it a series of horizontal rods 12, that carry guides 13,containing set-screws 14. 7

15 designates slide-rods movably mounted in the guides 13 and providedwith grooves 16, (see Fig. 1,) that are adapted to receive theset-screws 14 to prevent the rotation of the slide-rods, whilepermitting longitudinal movement thereof.

17 designates cake-receiving disks removably affixed to the upper endsof the sliderods 15 and having pivoted thereto a set of jaws 18. Thepoints of the jaws 18 project above the disks 17 to grip the cakesdeposited thereon, while their lower ends are seated in a grooved collar19. Between the disks and collars are expansion spiral springs 20, thetendency of which is to force the collars downwardly away from the diskswhen the collars are relieved from pressure, thereby causing the pointsof the jaws to be moved inwardly and grip the cakes that are deliveredonto the disks 17, as will hereinafter appear.

21 designates pushsfingers carried by the upper guides 13 and extendingvertically be side the disks 17.

The cakes to be iced are delivered to the disks 17 by depositing them ina chute 22, that terminates in a cup 23, suitably supported. The cup 23is provided in its wall with a slot 24:, through which the cakes maypass to fall onto the disks 17, the cakes being ejected through saidslot by the push-fingers 8o 21,that pass through the bottoms of thecups, as seen in Fig. I. At the time that the cakes are delivered fromthe cups 23 onto the disks 17 the-slide-rods 15 are in their lowermostpositions, (see Fig. 1,) and the weight of said rods counteracts theexpansion of the springs 20, so that the collars 19 are carried upwardlyon the slide-rods toward the disks 17, thereby causing the jaws 18 to beopened to receive the cakes. o

25 designates a turn-table mounted on the vertical shaft 9 near itsupper end and above the slide-rods 15 and parts carried thereby, thesaid table being arranged to rotate with said rods and parts. Theturn-table 25 is 5 provided with an annular rim and contains a series ofapertures 26, the size of which is diminished by removablereducing-rings 27, suitably applied to the turn-table and held byset-screws 28 or other means of fastening. 10o

29 designates a receptacle for the icing to be applied to the cakes,said receptacle be- (See Fig. 11.)

38 is a delivery-chute removably mounted upon branches of the arm 37 andinto which the cakes pass from the disks 17 after they have been iced.The upper end of the chute 38 is provided in its wall with a mouth 38*,

through which the cakes passinto the chute, (see Fig. I and dottedlines, Figs. II and IV,) and projecting downwardly from the chute at thelocation of said mouth is a pair of tongues 39, that are adapted to passunder the cakes on the disks 17 to receive them therefrom. As thetongues 39 pass under the cakes the push-fingers 21 press against thecakes and conduct them up the tongues into the chute 38,while thepush-fingers pass on through a slot 40 in the upper end of the chute.(See Figs. II and IV.) 41 designates a vibrating chute having it upperend arranged beneath the lower end of the delivery-chute 38 and arrangedto deposit the cakes in rows on a table or tray placed beneath the lowerend of the vibrating chute to receive them, thereby obviating thenecessity of the cakes being handled manually while the icing is moistthereon. The vibrating chute 41 is supported and rocked by a crank-shaft42, (see Fig. 11,) to which the upper end of the chute is connected, asseen in Fig. I. The upper end of the crank-shaft 42 is equipped with acrank-arm 43, that receives one end of a pitman 44. The opposite end ofthe pitman 44 is adjustably connected to a gear-wheel 45, mounted on theinner end of the arm 37 and arranged to mesh with a pinion 46 on thevertical shaft 9, and by which the gear-wheel 45 is rotated to impart arocking motion to the pitman 44 to rock the crank- 1 shaft 42 andvibrate the chute 41.

In the practical use of the machine the cakes are introduced into thechute 22 and cup 23 and delivered therefrom onto the receiving-disks 17in the manner hereinbefore described. As stated, the slide-rods 15 areat the time of the delivery of the cakes onto the disks 17 in theirlowermost positions, as seen at the right hand of Fig. I. As thevertical shaft 9 revolves and carries the sliderods 15 and disks 17therewith the lower ends of the slide-rods are brought onto the inclinedtrack 32, and riding up said track are raised to the position seen inFig. I at the left-hand side, during which the jaws 18 are caused togrip the cakes on the disks in the manner stated. When the disks areraised to their greatest elevation, they occupy positions immediatelybeneath the turn-table 25, at the location of the apertures 26 therein.At the same time the scraper 31 carries a quantity of icing from theportions of the turn-table between the apertures into the apertures andonto the cakes that are resting on the disks, with the result that thecakes receive the deposit of the icing. The turn-table continues torevolve, and the scraper 31 removes the surplus icing from the cakes andcarriesit onto the succeeding unapertured portion of the turn-table. Thecontinued rotation of the slide-rods and disks causes the slide-rods tobegin to descend on the inclined track 32, and when the collars 19 comeinto contact with the upper guides 13 the collars are raised, therebyopening the jaws 18 and freeing the cakes. At this time the disks 17 arebrought into juxtaposition with the tongues 39 of the delivery-chute 38,and said tongues pass under the cakes in the manner stated and thepush-fingers 21 press against the cakes and carry them up into the mouth38 of said chute for delivery through the chutes 38 and 41.

By the employment of the reducing-rings 27, removably applied to theturn-table 25 at the apertures 26, I provide for the adaptability of themachine to ice cakes of varying sizes, inasmuch as where the cakes areof small size reducing-rings having smaller aper tures therein may beutilized and where the cakes are of larger size reducing-ringscontaining larger apertures may be utilized. In

the same connection disks 17 of varying size 5 may be used, according tothe size of the cakes being iced.

By employing the adjustable spring-support for the inclined track 32 Iprovide for the vertical adjustment of said track, so that it may beraised or lowered to cause the sliderods to be elevated a greater orless distance with relation tothe turn-table 25, according to thethickness of the cakes being iced, so that the cake will be carried intothe aperture 26 to the proper extent to avoid escape of the icing as itis deposited onto the cake.

I claim as my invention 1. In a machine of the class described, thecombination of an apertured rotatable turntable, means located beneathsaid turn-table for receiving and carrying the cakes to be iced, meansfor automatically depositing the cakes on said carrying means, and meansfor causing said cake-carrying means to be elevated to the apertures insaid turn-table, substantially as described.
